Sending a break from minicom :)   That is, I just ask the MOP client to
stop loading.

Eventually I'll re-get all the sources and compile again. Adding a
timeout shouldn't be all that hard. It should be a matter of extending
the "connection" table by "last packet's recv/send time" and check this
table entry upon each new request.

Haven't seen that, but my interfaces tend to not go down (at least not
until the whole machine goes down...).
